SECTION III : MEDICAL AIRCRAFT
174. Medical aircraft shall be protected and respected as specified in the provisions of this document.
175. Medical aircraft shall be clearly marked with the emblem of the red cross or red crescent, together with their national colours, on their lower, upper and lateral surfaces. Medical aircraft are encouraged to implement the other means of identification set out in Annex I of Additional Protocol I of 1977 at all times. Aircraft chartered by the International Committee of the Red Cross may use the same means of identification as medical aircraft. Temporary medical aircraft which cannot, either for lack of time or because of their characteristics, be marked with the distinctive emblem should use the most effective means of identification available.
176. Means of identification are intended only to facilitate identification and do not, of themselves, confer protected status.
177. Parties to the conflict are encouraged to notify medical flights and conclude agreements at all times, especially in areas where control by any party to the conflict is not clearly established. When such an agreement is concluded, it shall specify the altitudes, times and routes for safe operation and should include means of identification and communications.
178. Medical aircraft shall not be used to commit acts harmful to the enemy. They shall not carry any equipment intended for the collection or transmission of intelligence data. They shall not be armed, except for small arms for self-defence, and shall only carry medical personnel and equipment.
179. Other aircraft, military or civilian, belligerent or neutral, that are employed in the search for, rescue or transport of the wounded, sick and shipwrecked, operate at their own risk, unless pursuant to prior agreement between the parties to the conflict.
180. Medical aircraft flying over areas which are physically controlled by the opposing belligerent, or over areas the physical control of which is not clearly established, may be ordered to land to permit inspection. Medical aircraft shall obey any such order.
181. Belligerent medical aircraft shall not enter neutral airspace except by prior agreement. When within neutral airspace pursuant to agreement, medical aircraft shall comply with the terms of the agreement. The terms of the agreement may require the aircraft to land for inspection at a designated airport within the neutral State. Should the agreement so require, the inspection and follow-on action shall be conducted in accordance with paragraphs 182-183.
182. Should a medical aircraft, in the absence of an agreement or in deviation from the terms of an agreement, enter neutral airspace, either through navigational error or because of an emergency affecting the safety of the flight, it shall make every effort to give notice and to identify itself. Once the aircraft is recognized as a medical aircraft by the neutral State, it shall not be attacked but may be required to land for inspection. Once it has been inspected, and if it is determined in fact to be a medical aircraft, it shall be allowed to resume its flight.
183. If the inspection reveals that the aircraft is not a medical aircraft, it may be captured, and the occupants shall, unless agreed otherwise between the neutral State and the parties to the conflict, be detained in the neutral State where so required by the rules of international law applicable in armed conflict, in such a manner that they cannot again take part in the hostilities.
